Origin

Latin honor is the source of honour and of honest and honesty (both Middle English). The idea that there is honour among thieves was expressed even in the early 17th century. The English philosopher Jeremy Bentham was the first to put it in print in its modern form when he wrote in 1802: ‘A sort of honour may be found (according to a proverbial saying) even among thieves.’ The plant honesty is named from its diaphanous seed pods, translucency symbolizing lack of deceit.
